Fig. 1 shows the realization flow of the means of communication between the application program that first embodiment of the invention provides, and details are as follows:
In step S101, dispose the shared file between two application programs, notify two application programs with the filename of shared file;
The purpose of file-sharing is to realize two equal accessible file of application program.In embodiments of the present invention, the file of sharing for need and two application programs are in the situation of same computer, because file all is resource sharings for all programs of this machine, need not to be provided with at this moment the shared attribute of file.As long as in the file of sharing for need and two application programs a situation that is not in same computer is arranged, as long as catalogue then is set to be shared, be mapped to network drive, just can realize of the visit of two application programs this document, thus the communication between the realization program.
In step S102, the write data application program is obtained data, and data are write shared file;
In step S103, the read data application program reads the data in the shared file.
Because third party's shared file is not subjected to the constraint of two application programs, if the write data application program does not in time refresh file, the data that will cause the read data application program to read are legacy data.Misread data problem for what the repeated use that prevents the factor certificate brought, make each data can only be between program communication once, in embodiments of the present invention, write data application program identical file of spanned file name all when each write data, if had this document under the share directory, then covered the original refresh data.
The file that needs only this filename of visit for the read data application program is a readable data, but because the each write data of write data application program all generates the file of same file name, if the not timely refreshing file of write data application program, can exist the read data application program to misread the problem of legacy data, therefore adopt the i.e. mode of deletion that reads, after read data application program success reading of data with file delete, guaranteed each data can only be between program communication once.
Fig. 2 shows the realization flow of the means of communication between the application program that second embodiment of the invention provides, and details are as follows:
In step S201, dispose the shared file between two application programs, notify two application programs with the filename of shared file;
In step S202, the write data application program is obtained data;
In step S203, the write data application program judges whether there are data of the same name under the share directory, is execution in step S204 then, otherwise execution in step S205;
In step S204, the write data application program covers refresh data with the data of the same name under the share directory;
In step S205, the write data application program writes shared file with data;
In step S206, the read data application program reads the data in the shared file;
In step S207, after the data read success, the data in the read data application program deletion shared file.
